Subject: [PATCH] net: airoha: fix CONFIG_DEBUG_FS check

From: Arnd Bergmann <arnd@...db.de>

The #if check causes a build failure when CONFIG_DEBUG_FS is turned
off:

In file included from drivers/net/ethernet/airoha/airoha_eth.c:17:
drivers/net/ethernet/airoha/airoha_eth.h:543:5: error: "CONFIG_DEBUG_FS" is not defined, evaluates to 0 [-Werror=undef]
  543 | #if CONFIG_DEBUG_FS
      |     ^~~~~~~~~~~~~~~

Replace it with the correct #ifdef.

Fixes: 3fe15c640f38 ("net: airoha: Introduce PPE debugfs support")
